The descriptive statistic results show that air temperature values on the horizontal plan which absorbed IR radiation trended to increase when the plan was close to the emitter, but temperature distributions were at wide range. On the other hand, the uniformity of air temperature distribution as appeared with the installed emitter away from the radiation absorbing plan, especially at the distance of 0.4 m between emitter and absorbing surface at each emitter temperature level, air temperature distribution seem uniform as shown as low variance values.
